Integral Challenges in Construction by Helen Marian Guerra Gonzalez

TRANSPORT

The transportation of materials used for coastal works is carried out by road, railway or water.

Furthermore, each transport method can be subdivided into:

helenguerra — 2024-10-02 19:06:39 UTC

One which merely delivers materials to a particular site

One in which the means of transport is used as a method of construction.

The choice of transport system is fundamental in planning the construction phase of the works, so the decision process should not be based solely on price, but should also consider factors such as:

• Existing infrastructure at the site

• Location and geography of the site

• Preferred rate of delivery

• Environmental constraints

etc.

Road transport

The following vehicle types are commonly used for the transport of quarried rock.

Flat-bed lorries
Steel-bodied tippers and on/off-road dump trucks
Conventional aluminium alloy tippers
On-site vehicles

Rall transport

This form of transport can be attractive when a quarry is identified that has its own railhead, and where the project is able to make use of a nearby rail facility that is able to accommodate the discharge of trains.

Waterborne transport

Waterborne transport can often be utilised to bring in quarried materials to work sites.

The main benefit of this method is that large quantities can be brought to the site relatively quickly and with little disruption to the local onshore environment.

CONSTRUCTION RISK AND SAFETY

Coasal and estuarine construction is particularly hazardous because of the hostilel and sometimes unpredictable nature of the environment.

helenguerra — 2024-10-02 20:04:53 UTC

The subject of risk management has received increased attention from industry, academia and government, as it can help to:

• identify and question the assumptions that affect the success of the project

• balance the costs and benefits of the risk controlling measures

• protect the health and safety of the operatives and the public

Etc.

GROUND AND SOIL ISSUES

Ground conditions

For all work methus alis necessary to ascer tam the stabily of both the structure and tho subsoil.

Erosion and sedimentation

helenguerra — 2024-10-02 20:11:39 UTC

Core material and/or underlayers that are prone to crosion should be covered early to reduce to a minimum the losses caused by current and wave action.

helenguerra — 2024-10-02 20:15:40 UTC

Soil erosion may occur during construction because of flow contraction around progressing structures such as breakwaters, groynes, closure dams and bridge abutments. For this reason it is advisable to install a bottom protection before starting construction with land-based equipment.
